The input voltage range includes ground for single- 3 100k CD4011 supply operation and V for split supplies. A low power 1/4 supply current of 2 mA, which is independent of supply voltage, CMP04 makes this the preferred comparator for precision applications 12 requiring minimal power consumption. Maximum logic inter- face flexibility is offered by the open-collector TTL output. Figure 2a.
